Abstract

Mung bean (Vigna radiata L.) is the third most essential legume crop commodity after soybeans and peanuts. Mung bean production faced problems of nutrient-poor land and soil texture that does not support soybean growth. The solution to overcome these obstacles is the application of mycorrhizae in nutrient-poor soils. This study aimed to determine the effect of various inoculums and mycorrhizal doses on growth and production in mung beans. This study used a Completely Randomized Design with nine treatments and three replications. The research included mycorrhizal inoculation with various treatments, as well as observations with variable plant height, plant biomass, number of pods, wet weight and dry weight of pods, the weight of 50 wet and dry seeds, mycorrhizal infection in roots, and number of spores in 100 gr of soil. The data were analyzed by SPSS 15.0 program for ANOVA. The results indicated that granular (30 gr) had the highest plant height of (41.33 cm), crown weight (30.69 gr), number of pods, wet and dry pod weight is 13.66, 9.84 gr, and 8.86 gr, respectively, 50 kg of wet and dry weight (3.82 and 3.20) and the highest effect on the number of spores at 29.33. The 30 gr tablets treatment showed the highest results on root weight (22.98 gr), while the 30 gr mixture showed the highest results on the percentage of infection (73.33%).

Abstract

Cabbage is one of the commodities that mostly cultivated in Indonesia, but the cabbage farmers often suffered losses because of pests' attack. The important pests on cabbage is Plutella xylostella. This study aimed to investigate the effectiveness level of an insecticide with active ingredient carbaryl 85% in controlling P. xylostella which attacks cabbage and its impact on the parasitoid of Diadegma sp. This research uses a randomized block design with six treatments and four replications. The treatments were different concentrations of the insecticide carbaryl 85%. The testing on Diadegma sp. used two methods, directly and indirectly test (residual exposure). The carbaryl 85% was not effective in controlling P. xylostella, but the population was decreasing. The carbaryl 85% with the highest effect in reducing P. xylostella population was 3.0 g/l. The carbaryl 85% did not affect on the mortality of natural enemies (Diadegma sp. parasitoid) after direct and indirect test.

Abstract

Various negative impacts of pesticides must be avoided by applying management principles that have as little negative impact on the environment as possible using an integrated pest management (IPM) approach. This study aimed to examine the diversity of arthropods and the feasibility of farming in IPM and conventional fields on soybeans. Arthropod sampling was carried out in September–December 2021 using a yellow pan trap, yellow sticky trap, and visual methods. The arthropod population found was analyzed using the T-test, and the level of arthropod diversity was calculated based on the diversity index (H'), species richness index (R), evenness index (E), and dominance index (C). The feasibility of farming on both fields was calculated using the R/C ratio and BEP prices. The results showed that the number of arthropods in IPM and conventional fields was significantly different. In both fields, the diversity index value was in the medium category, the species richness index value and the evenness index value were in the high category, and there was no dominance in both fields. Even though it belonged to the same category, the index value of arthropod diversity in the IPM field was higher than in the conventional field. In IPM and conventional fields, the R/C ratio values were 1.01 and 1.06, respectively, while the BEP value in IPM and conventional fields was IDR 10,601.44 and IDR 10,075.14.

Abstract

Green ladybug Nezara viridula (Hemiptera: Pentatomidae) is one of the harmful pests on soybeans. One of the ways to suppress attacks is by using phosphate fertilizers. The effect of applying phosphate fertilizer could be seen using biological parameters and demographic statistics. The research was conducted at the Pest and Wirehouse Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Brawijaya University, from January to June 2022. The experimental design in this study used Completely Randomized Design (CRD) in the laboratory and wired house. There were four treatment doses of phosphate fertilizer consisting of 0 kg/ha (control), 25  kg/ha (low), 50 kg/ha (recommendation), and 75 kg/ha (high). Observations were made on 90 individuals of N. viridula in each treatment divided into three replications. The type of phosphate fertilizer used in this study was SP36 fertilizer. The observational variables of this study were the biology and demographic statistics of N. viridula. Observations were made daily, and the data were compiled in a live table. Calculations were carried out using demographic statistics and analysis of variance to determine differences between treatments using HSD 5%. The results showed biological and demographic statistical differences in N. viridula: personality, life cycle, and gross growth rate (GRR). These findings have significant implications for pest management in soybean cultivation, suggesting that applying phosphate fertilizers can effectively suppress the attacks of N. viridula, particularly at the recommended dose.

Abstract

Different cultivation techniques for rice (Oryza sativa L.) are known to affect arthropod populations and diversity levels. This research was conducted to study how arthropod diversity can be affected by different cultivation techniques. The research was carried out from October 2022 to March 2023. Arthropod diversity observations were carried out in the organic rice field of Kampung Pertanian Organik Brenjonk and a conventional rice field belonging to a farmer in Penanggungan Village, Trawas District, Mojokerto Regency. Data were collected weekly for 12 observations. Arthropods were collected using passive methods, such as pitfall and yellow sticky traps, and active methods, such as sweep netting and handpicking. The data were analyzed to assess the diversity level. The results showed more arthropods in the organic rice field, with 1815 individuals consisting of 4 classes, 13 orders, 52 families, 70 genera, and 74 morphospecies. In contrast, in the conventional rice field, 1028 individuals were found, consisting of 3 classes, ten orders, 28 families, 32 genera, and 33 morphospecies. The calculation results of arthropod diversity levels showed that the organic field is better than the conventional field.

Abstract

Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) is an invasive pest originally from Central America. The S. frugiperda attack was first documented in Indonesia in 2019. Due to its voracious feeding habits, S. frugiperda can lead to significant losses. This study aims to provide insights into the  developmental patterns, births, and deaths of S. frugiperda, utilizing corn as the main host and spinach as an alternative host. The research was conducted at the Pest Laboratory and wire house of  Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya from February 2023 to April 2023. This study included two treatments and ten replicates, requiring a total of 500 eggs with 25 individuals for each replicate. The results showed that the survival curve and survival rate of S. frugiperda in both treatments were classified as type I curves. The values of gross reproduction rate (GRR), net reproduction rate (Ro), intrinsic growth (r), and average generation length (T) in corn leaves were 1,280.20; 518.48; 0.27; 30.79, respectively.  In contrast, the corresponding values for spinach leaves were 927.09; 322.15; 0.21, 36.23. Based on the biological data and demographic parameters, it  can be concluded that spinach plants  may serve as viable as alternative hosts for S. frugiperda.
